LUBRICATOR.-

SPECIFICATION forming part of yLetters Patent No. 552,194, datedDecember 31, 1895.

Application nea August 14,1894. Seriana 520,322. (No moda To a/ZZ whomit may concern.-

Be it known that I, JOHN W. MORGAN, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented a new and useful Pipe-Oiler, of which the following is aspecification.

My invention relates to lubricators, and it has for its obj ect toprovide a device adapted for use in oiling machinery at a plurality ofpoints from a common tank or reservoir by means of feed-tubescommunicating with the tank, and, furthermore, to provide an improvedfeed-nozzle so constructed as to facilitate its application to thefeed-tube at any desired point, whereby the tube may be tapped for anozzle and the nozzle arranged in operative position with the minimumloss of time.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claim.

In the drawings, Figure lis a vertical section of a tank, feed-pipe andnozzle constructed in accordance with my invention. Fig. 2 is a detailvertical section of the lower member of the feed-nozzle, including thevalve-seat and the sight-tube; Fig. 3 is a detail side view of thestrainer.

Similar letters of reference indicate corresponding parts in all thefigures of the drawings.

In an apparatus embodying my invention, A represents a tank incommunication with a main feed-tube B having a stop-cock C, and withinthe tank is arranged a strainerD having1 a depending sleeve E, whichsurrounds the projecting extremity of the feed-tube to prevent lint andsediment from entering the feed-tube. Communicating with the tank at itsbottom is a trap F and mounted upon this trap is a gage G to show thequantity of oil in the tank. The trap is adapted to catch any waterwhich may be contained in the oil, and the water may be drawn Off byremoving the screw-plug H without interfering with the operation of theoiler. Communicating with this main feed-tube may be any desired numberof branch feed-tubes J, suitable couplings I being arranged at thepoints of intersection. The outer extremities of the branch feed-tubesare provided with removable closures N.

The feed-tube maybe tapped at any desired point or points for theapplication of nozzles, and the nozzle embodying my invention comprisesupper and lower members P and S, respectively, each of which is providedwith a threaded tip t adapted to be threaded in registering perforationsin the upper and lower sides of the tube. The tip of the upper member isformed integral with a guide P', in which is mounted a tubularvalve-stem O. Said valve-stem is preferably threaded in the guide, and astuffing-box P2 is arranged upon the guide to prevent leakage. The stemterminates at its upper end in a hand-wheel P3, and a removable plug Qis secured in the upper end of the bore of the stem to close the same.The tip t of the lower member is provided with a valve-seat S to receivethe valve which is formed by the rounded or ground lower extremity ofthe valve-stem, and said tip forms a part of a tubular conductor S2having lateral iianges S3. Said lateral flanges are secured in contactwith the upper end of a sight-tube T by means of a screw-cap S4, saidsight-tube being provided with lateral openings V closed by atransparent guardU arranged within the tube. The sight-tube is providedat its lower end with a communicating outlet-nipple S5.

From the above description it will be seen that the improved nozzle maybe applied to a feed-tube by boring and threading registering openingsin the upper and lower sides of said tube and screwing the tips tof themembers of the nozzle thereinto, thereby facilitating the application ofthe nozzle and enabling the Same to be accomplished with the minimum`loss of time in operating machinery. The tubular conductor or dropperS2, which conveys the lubricant from the feed-tube whe'n the valve isunseated, has its bore ar- .ranged in vertical alignment with the boreof IOO ple S5 to remove any accumulations of dirt or sediment thereinand secure the proper flow of oil.

A further advantage of the sectional construction of the improvedlubricator resides in the fact that the valve-stem, which extendstransversely across the bore of the oil-tube, is of such diameter as toavoid interference with the iiow of oil past the lubricator. Hence aplurality of lubricators embodying my invention may be applied to thesame tube without so obstructing the flow of oil as to prevent thosenear the end of the line from receiving sufficient oil to preserve aconstant How.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacriiicin g any of the advantages of this invention.

Having described my invention, what I claim is- In a lubricating device,the combination with a feed tube adapted to communicate with an oilreservoir or tank, of a nozzle comprising independent upper and lowermenibers arranged in axial alignment, respectively7 above and below thefeed tube and provided with tips threaded in registering` openings inthe upper and lower sides thereof, the lower member of the nozzle havinga conductor or dropper in communication with the feed tube and providedcontiguous to its upper end with a valve-seat, and the upper meinber ofthe nozzle having an axially movable valve-stem terminating at its lowerend in a valve adapted to fit said seat, whereby in order to attach thenozzle to the feed tube aligned openings are formed in the upper andlower sides thereof and the tips of the nozzlemembers are screwed insaid openings, the valve-stem being of such diameter as to extendtransversely through the tube without interfering with the iiow of oilpast the lubricator, substantially as specified.

In testimony that l claim the foregoing as my own I haveV hereto afiXedmy signature in the presence of two witnesses.
